I'm not sure if that's what I had done or not. Anyway what they did for me was inject me with radio active iodine and I had to lay on a table for a really long time with this thing around the upper part of my body. I think i could see out the side, but i couldnt move, if i did it would have messed things us and we would have started all over again! I was pregnant at the time so it was VERY uncomfortable.
